To succeed in a tough marketplace, small businesses must be accessible, without significant interruption, even in the most adverse situations. This kind of ongoing accessibility is an important aspect of business continuity — a critical success strategy that doesn’t just happen, but requires proactive planning.

This paper will explore how different kinds of interruptions can adversely affect an SME’s business continuity and illustrate how, through advanced features such as resiliency and mobility, Avaya’s IP Office can help SMEs overcome interruptions and maintain business continuity.
